The poll said

Democrat 48% · Republican 43%

D+5.0

The certified result

Democrat 47.95% · Republican 49.73%

R+1.8

The arithmetic

  1. Poll margin = 48 − 43 = 5.00
  2. Actual margin = 47.949 − 49.728 = -1.779
  3. Signed miss = 5.00 − (-1.779) = 6.779
  4. Absolute miss = |6.779| = 6.779

The poll overstated the Democrat by 6.8 points and had the wrong leader.
